Sam invests $6,000 in a savings account at 6%
for 3 years. How much did he earn in interest?
answer: $1,080
explanation: interest = principal x rate x time
>> interest = 6,000 x 0.06 x 3
after multiplying, you get 1,080, which is the simple interest
**tip: turn the rate/percent into a decimal, then multiply

Billy is going on a road trip. The amount of gas g (in gallons) left in his tank varies inversely with the amount
of time he has been driving t in hours. He has 10 gallons left after 4 hours. Write the equation for this
situation.
40
Answer:
The equation to represent the situation is [tex]10 = \frac{k}{4}[/tex]
Step-by-step explanation:
It is given that:
Amount of gas left in tank varies inversely with the amount of the time.
Let,
g represents the gas
t represents the time
g ∝ 1/t
[tex]g = \frac{k}{t}[/tex]
Here, k represents the constant of proportionality.
Putting g = 10 and t = 4 in the equation
[tex]10 = \frac{k}{4}[/tex]
Therefore,
The equation to represent the situation is [tex]10 = \frac{k}{4}[/tex]

A plane descended an average of 200 feet per second for 15 seconds. How far had the plane descended at the end of the 15 seconds?
Answer:
3000 ft
Step-by-step explanation:
If we're going 200 ft per one second, that means, to find the distance after 15 seconds, then we have to multiply:
200 fps (feet per second) x 15 seconds = distance.
Distance = 3000 ft

10e=1
What does E equal cause i need help
The value of e is 0.1 in the equation 10e=1.
In the equation 10e = 1, the letter "e" represents an unknown variable.
To find the value of "e," you need to isolate it on one side of the equation.
Divide both sides of the equation by 10:
(10e) / 10 = 1 / 10
This simplifies to:
e = 1/10
e=0.1
Hence, the value of e is 0.1.

Solve for x: 9x - 3 - 8x = 7 - x O O A. X=-7 O B. x = -2 D c. x=4 (0) O D. X = 5.
9514 1404 393
Answer:
D. x = 5
Step-by-step explanation:
Add x+3 to both sides and simplify.
9x -3 -8x +(x +3) = 7 -x +(x +3)
2x = 10 . . . . . simplify
x = 5 . . . . . . . divide by 2
__
As you can see, the expression we chose to add (x+3) is the one that results in variable terms being separated from constant terms after simplification.

The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t > 3 represents time in seconds. If the car traveled for t − 3 seconds, identify the expression that represents the speed of the toy car.
Answer:
[tex]t^2+1[/tex]
Step-by-step explanation:
We are given that
Distance traveled by a toy car
[tex]D(t)=t^3-3t^2+t-3[/tex]
Where t>3
Time taken by car =t-3 seconds
We have to find the expression which represents the speed of the toy car.
We know that
[tex]Speed=\frac{Distance}{time}[/tex]
Using the formula
[tex]Speed=\frac{(t^3-3t^2+t-3)}{t-3}[/tex]
[tex]Speed=\frac{t^2(t-3)+(t-3)}{t-3}[/tex]
[tex]Speed=\frac{(t-3)(t^2+1)}{t-3}[/tex]
[tex]Speed=t^2+1[/tex]
Hence, the expression which represents the speed of the toy car
[tex]t^2+1[/tex]
The expression that represents the speed of the toy car is [tex]t^2 + 1[/tex].
The calculation is as follows:Given that,
The distance traveled should be [tex]D(t) = t^3 - 3t^2 + t - 3[/tex]
Here t>3
Time taken by car = t -3 seconds
Now the expression should be
[tex]Speed = Distance \div time\\\\= ( t^3 - 3t^2 + t - 3) \div (t - 3)\\\\= t^2(t - 3) + (t - 3) \div (t - 3)\\\\= (t - 3) (t^2 + 1) \div (t - 3)\\\\= t^2 + 1[/tex]

tan 235° = 2tan20°+ tan215°
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215
